That's for the mods to decide actually, but I strongly recommend you to remove it if you won't get more than few users or if it's activity will be really rare and there won't be any constructive discussion, jst some whining about leet speak. Once Ralle already limited social group creation. If the group spam will happen again, he might decide to completely get rid of groups, this time forver and with no compromises, so I somewhat recommend not to make any groups that have love chance of becomming active or constructive...
